Definitions
- This invention is directed to hose rewinding apparatus for flexible hoses. More specifically, the present invention relates to a direct current powered, motor driven hose rewinding apparatus with manual override that is mounted within a protective safety enclosure.
- the safety enclosure includes a telescoping handle and a pair of wheels for easy transport and storage.
- the prior art has proposed a number of different structures for rewinding and storing a hose when it is not in use.
- These devices generally include stationary hose reel hangers that can be mounted to a surface of a building, such as an outer wall of a house, or portable hose reel carts that permit ready transport of the hose from one location to another.
- hoses and the like In the past it was common to retrieve hoses and the like by manually winding them around a suitable structure, such as a wall mounted hanger, or simply bundling them into loose coils.
- a suitable structure such as a wall mounted hanger
- Surface (or wall) mounted hose reels or hangers come in a wide variety of configurations.
- one surface mounted hose hanger includes a simple, semi-circular metal or plastic support that is mounted to the building, over which the hose is looped or hung.
- Another surface mounted device or reel includes a rotatable fitting that is mounted to the building surface to which a manually rotated reel is mounted.
- hose is pulled out from such manually wound devices, it often becomes snarled or tangled and requires appreciable time and effort to correct the situation.
- these surface mounted reels and hangers are often considered unsightly, particularly if they are mounted to the front of the building and are not covered or otherwise obscured by plants or foliage.
- Portable hose reel carts permit ready transport of the hose from one location to another.
- Portable hose reel carts typically include an open, manually rotatable reel or spool positioned between a pair of side frames with wheels. The hose is manually wound upon the reel for storage and pulled or dispensed from the reel for use.
- Portable hose reel carts may also be considered by some to be unsightly. Given that most hose reel carts are designed for use in and around garden and lawn areas, it is expected and natural for these carts to become dirty. As such, some users may be inclined to constantly remove a hose reel cart, particularly from the front of a house, when, for example, the cart becomes dirty, muddy or discolored.
- hose retrieval devices which automatically retrieve and rewind hose on a reel in such a manner so as to avoid tangling the next time the hose is deployed or paid out.
- Such devices generally include a reel and a level wind mechanism for guiding the hose onto the reel.
- the level wind mechanism includes a traversing screw, a guide rod, and a follower.
- the reel is generally directly driven by a motor and/or an intermeshing clutch assembly.
- the electric motors of the prior art devices have voltage requirements that reduce portability and increase the risk of electrical shock.
- the clutch mechanisms utilized on these devices are either completely engaged or completely disengaged and lack an infinitely adjustable torque transfer assembly to allow operator controlled speed and/or force of hose retrieval.
- a rechargeable battery operated motorized hose rewinding and storage device that permits safe motorized take-up and manual dispensing of a hose that is also aesthetically pleasing.
- Such a hose rewinding and storage device that can be safely used to retract and “hide-away” the hoses stored therein when not in use.
- the hose rewinding device should also be constructed for easy transport and storage while maintaining a overall compact profile.
- a number of hose rewinding assemblies in the prior art utilize electric motors to drive a reel for retracting an elongate member such as a cord or hose. Examples are disclosed as follows:
- U.S. Pat. No. 4,832,074 discloses an automatic hose rewinding device having an alternating current (AC) motor driven reel.
- the desired amount of hose is pulled out of the enclosure manually for use.
- a button is pushed once and the hose is completely retracted until a device on the end of the hose strikes a bar to disengage the AC motor.
- the design of the device does not allow small increments of the hose to be retracted. If the operator wishes to use a smaller amount of hose, the entire hose must be retracted and the desired amount of hose must be manually pulled out again.
- the use of alternating current reduces portability of the device and increases the risk of electrical shock.
- U.S. Pat. No. 4,513,772 discloses an automatic hose winding apparatus having an intermeshing, non-slipping clutch.
- the desired amount of hose is pulled out of the enclosure manually for use.
- the operator For retraction, the operator must manually lock the intermeshing clutch mechanism in place.
- a device on the end of the hose strikes a lever to disengage the intermeshing clutch.
- the design of the device allows increments of the hose to be retracted, however, the operator must manually disengage the clutch before any amount of hose can be manually payed out.
- the apparatus makes no disclosure or suggestion of a protective enclosure or a disengaging hose guide.
- U.S. Pat. No. 5,495,995 discloses a motor driven hose reel assembly.
- the device interconnects two sensors and a motor to monitor the quantity of hose manually pulled from the reel. By pulling on the hose manually, the hose is rewound in an amount less than that necessary to completely rewind the hose. Because the device is operated in a retraction direction when the hose is pulled, the design requires the operator to overcome the pulling force of the device to extend hose from the machine.
- U.S. Pat. No. 4,012,002 discloses a coupling mechanism for use in conjunction with a hose reel to automatically and selectively engage or disengage the reel and motorized drive train.
- the coupling utilizes a sliding spring pin on the drive train which is designed to automatically engage one of a series of cooperating stop lugs on the reel to transmit the driving power of the motor to the rotatable reel.
- the spring pin can be manually locked in a disengaged position to allow the hose reel to freewheel. When the spring pin is engaged the device operates in direct drive from the motor.
- U.S. Pat. No. 6,149,096 discloses a retractable reel device especially useful for electrical cables.
- the device is specifically designed to allow an operator to pull out a desired amount of cable. Once the cable is paid out, the device maintains a predetermined amount of tension on the cable. Thereafter, any slack in the cable is automatically retracted by an AC motor.
- references are further deficient in teaching the use of a rechargeable battery in combination with a direct current (DC) motor for powering the hose retrieval device.
- the references are deficient in teaching an enclosure with safety interlocks that prevent the motor from being engaged when a cover is in an open position.
- the devices are further deficient in teaching a safety hose guide assembly that is capable of disengagement in the event that the path of the device is inadvertently blocked.
- the prior art devices are still yet deficient in teaching a motorized hose rewinding device with manual override, allowing the hose to be retracted manually as well as by motor. Even further, the prior art devices are deficient in teaching a device which includes a telescoping handle and a pair of rearwardly mounted wheels for easy transport of the device.
- the present invention provides an improved direct current powered hose rewinding device having an enclosure including a telescoping handle and a pair of rotatably mounted wheels to provide portability. Additional features include various embodiments of infinitely variable torque transfer assemblies which cooperate with the direct current motor for power-assisted hose retrieval.
- the apparatus includes a motorized rotatable spool carried and contained within an enclosure.
- the rotatable spool includes a hub and a pair of flanges at opposing ends of the hub, and is configured for storage, motorized take-up, and manual pay-out of the flexible hose.
- Power for the motorized spool is supplied through a control assembly that includes a rechargeable battery, a main power switch, and at least one safety interlock.
- the safety interlock(s) are incorporated into the enclosure and prevent motorized operation of the spool when the enclosure is opened.
- the enclosure has left and right side wall panels, front and rear wall panels extending between the left and right wall panels, and a cover.
- the enclosure is configured for receiving a rotatable spool for storing a length of flexible hose within the enclosure.
- the cover pivots about a pair of hinges that mount the cover to the enclosure for movement between a closed position and an open position.
- the hinge arrangement includes hinge pin bosses extending upwardly from a top edge of the rear panel, wherein a hinge pin extends from each of the hinge pin bosses about laterally and in axial alignment with respect to each other.
- the cover is formed having a depending lip and a pair of pockets that are integrally formed into the rear wall of the depending lip for cooperation with each respective hinge boss and pin.
- the pins are formed as fluted cylindrical elements extending from the bosses, axially aligned to one another to facilitate rotational movement.
- a safety interlock switch assembly prevents motorized operation of the hose spool.
- an engagement pin extending from the underside of the cover cooperates with the safety interlock switch to allow motorized operation of the spool.
- the front wall panel includes a cut-out portion extending downward from the top edge thereof adjacent to the junction with the cover. In this arrangement, when the cover is closed, the cut-out accommodates traversing a portion of the flexible hose therethrough.
- a reciprocating hose guide assembly is linked to the spool.
- the reciprocating hose guide will move back and forth across the spool to uniformly and smoothly wrap the hose on the spool to provide a compact storage configuration.
- the reciprocating hose guide can be released from its double-helix lead-screw in the event that its path becomes blocked, such as by debris or when a hand or arm is mistakenly placed in the opening.
- the hose guide may be manually disengaged to facilitate easy hose pay-out, and can thereafter be repositioned before being manually re-engaged.
- a sliding seal fluid inlet joint permits the hose outlet joint to rotate with the hose spool without disconnecting the hose. This arrangement permits rotating the spool without twisting or torquing internal components, while maintaining sealed fluid communication between the water supply and the hose.
- the spool is provided with a winding means capable of manual rotational movement of the spool in relation to the enclosure and an electrically energized power assist means for selective and operative engagement of the winding means.
- the winding means is illustrated as a hand crank extending through the enclosure and connected to the spool at about its axis of rotation.
- the power assist means is illustrated as a DC powered motor mounted within the enclosure and connected to the hose spool via a torque transfer assembly.
- the torque transfer assembly utilizes a dynamic clutch assembly to transfer torque from the motor to rotate the torque transfer assembly thereby rotating the spool.
- the clutch assembly may regulate torque supplied to the spool via a foot pedal operated clutch assembly.
- the foot operated cantilever forces an idler friction wheel into engagement with a drive friction wheel and a spool friction wheel to selectively couple and decouple the DC motor to and from the spool to modulate the pulling force and rotational speed of the hose spool.
- the main power switch of the control assembly supplies current from the battery to start the DC motor and the idler friction wheel is forced into engagement to provide the desired speed and/or force required for hose retrieval. Release of the pedal stops the motor and allows hose to be freely pulled from the spool as desired.
- the foot operated cantilever forces an idler gear into engagement with a drive gear and a spool gear to selectively couple and decouple the DC motor to and from the spool to modulate the pulling force and rotational speed of the hose spool.
- the main power switch of the control assembly supplies current from the battery to start the DC motor and the idler gear is forced into engagement to provide the desired speed and/or force required for hose retrieval.
- Release of the pedal stops the motor and allows hose to be freely pulled from the spool as desired.
- the device may also include at least one idler gear to adjust torque and rotational speed of the hose spool with respect to the motor.
- the DC motor may include an internal gear train coupled between the armature of the DC motor and the DC motor output shaft.
- the internal gear train is capable of reducing RPM output and increasing motor torque.
- Power for the control assembly is provided by a removable, replaceable, and rechargeable battery assembly conveniently stored within its own closed compartment in the enclosure. Connection to the battery is made via a unique clip-on connector that also provides an integrated battery charging jack.
- the clip-on connector is constructed and arranged to prevent the clip from being incorrectly connected to the battery and the assembly requires directional installation into the enclosure for electrical connection to the control assembly.
- the integrated charging jack in the clip-on connector allows convenient battery recharging without disconnecting the clip from the battery. In this manner the battery can be safely and easily removed, recharged, and/or reinstalled into the enclosure without danger of incorrect connection.
